ABSTRACT:
The invention relates to an arrangement for actuating a slide-gate nozzle which is installed on the bottom of a casting ladle. This arrangement comprises a cylinder/piston unit which is operated by means of a pressure medium. Elements of a coupling are, in each case, assigned to the cylinder and to the stationary portion of the slide-gate, on the one hand, and to the piston rod and to the movable portion of the slide-gate of the slide-gate nozzle, on the other hand, these elements being in engagement when in the operating position. The invention embodies the combination of the following features, namely that the elements of the first coupling comprise a quarter-turn fastener, this coupling being assigned to the stationary portion of the slide-gate, and to the cylinder, and that the elements of the second coupling comprise a latching mechanism of the snap-in type, this coupling being assigned to the movable portion of the slide-gate, and to the piston rod.
